restoring a fuel pump

[Keith B.]

Scored a real 40083 fuel pump for a 65 L76. Its fairly dirty and grimy. What is the best way to clean and look new. And most important are all rebuild kits the same.

Hey Keith, can I ask where you found this? Looks like a great find.

The rebuilding kits are not all the same. I sent my original 40083 core to Steve Hack to be rebuilt. It now runs great!

Nice find. Does it say AC on the top?

Kits are probably not all the same and I don't have a recommendation but the diaphragm is the most important abviously - but equally important to follow the procedure in your service manual -"Diaphragm must be flexed to its full stroke while tightening cover screws ......"

When you open it up please take lots of pictures of numbers on main housing so we can add to past information, ty

Re: restoring a fuel pump

I attempted to have my fuel pump recolored. It didn't work out well. I would clean it up and rebuild it as is. Just my personal opinion especially as good as your pump looks.
The rebuild is not bad after you figure out how the diaphragm unhooks from the pivot. The kit I used had different springs than the original. I reused the originals. The spring can affects the fuel pressure.

What make you think this top section of the pump is original configuration? The casting near the vent hole is rounded, s/b angled into the main body.
Missing the AC logo on tower. As for the finish it looks as it should. Ring on pivot pin looks big maybe from previous rebuild.

Keith,

Gene is talking about the AC logo at the top of the "tower" in your photo from your pasting at 6:57AM on Nov 18. I think he asked because the logo is not obvious in the photo from your posting that started this thread.

Keith,

A 40083 pump in the original, production configuration for C2s is a challenge to find. The ones that show up on e-bay can have cast or stamped bottom pieces, can have AC embossed on the cast bottom or not, can have reinforcing bars supporting the tower, or not, can have AC embossed on the top or not, can be stamped with 40083 on the flange or not. It's a challenge to remember all those things and to know what's right for your car. I'm going to see if I have the 2010 Restorer article to refresh my memory.

Re: Restoring a fuel pump...

Keith,

I made a BIG mistake into buying a "reconditioned" fuel pump from that Goat Hill Classics guy. I installed it and it ran OK for a couple months. Then this past August, I went out into the garage to drive my '57 up to Carlisle and the whole garage reeked of gasoline. I checked under the engine and sure enough there was this big puddle of gas under the engine. Needless to say, my trip was cut short as well as the $105 I paid for vendors spot. Just beware.
